MlLLSTONE-DRIVER.

SPECIFICATION forming part of Letters Patent No. 252,557, dated January17, 1882.

Application filed July 8, 1881.

To all whom it may concern:

Be it known that I, LEWIS P. WEABER, Jr., of New Harmony, in the countyof Posey and State of Indiana, have invented certain new and usefulImprovements in Millstone-Drivers; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification.

My invention relates to an improvement in millstone-drivers and 'itconsists in the combination of a ring or band which is passed over thespindle, and which is provided with two dowel-pins to fit in the topplate, with a driver which is made in two parts, and which parts arepivoted between the two parts of the frame, as will be more fullydescribed hereinafter.

The object of my invention is to make a cheap, simple, and efficientdriver for millstones, and one which is so constructed that theslightest movement of one part of the driver will react upon the other,and thus keep the stones even and true.

Figures 1 and 2 are vertical cross-sections of my invention, taken atright angles to each other, and Fig. 3 is a horizontal section of thesame.

A represents a ring or band which is passed down over the spindle, andwhich is provided with two tapering dowel-pins, B, upon its top edge,for the purpose of catching in correspond- (No model.)

ing recesses made in the top plate, 0, for the purpose of holding thering and the plate securely together. This ring is made L-shaped incross-section atits edges, as shown in Figs. 1 and 2, and passing upthrough the top plate and the horizontal flange which extends outwardfrom the lower edge of the ring are the two pivotal bolts D, upon whichthe two parts of the driver G turn. This driver is made in two parts ofthe form shown in Fig. 3, and each one has its inner end so shaped as tobear against the sides of the ends of the other part. As thus held thetwo parts of the driver are placed between the top plate and the ring orband, and have a free limited lateral movement upon their pivots. Theslightest movement of either part is at once transferred to the oppositepart, and this reflex action serves to keep the stone always even andtrue.

Having thus described my invention, I claim The combination of theL-shaped ring or band A, provided with the dowel-pins B, the top plate,(J, the pivotal bolts D, and the driver G, made in two parts and havingtheir ends bear against each other, so that the slightest movement ofonepart will react upon the other, substantially as described.

In testimony whereof I afllx my signature in presence of two witnesses.
